Blog:Experts blame growing portion sizes for obesity

A team of researchers from the University of Cambridge have blamed increasing portion sizes in the UK for obesity.

Data published in the Cochrane Database of Systematic Reviews by a team of experts that reviewed 61 studies suggests portion size affects how much we eat. The team said people were "reluctant" to leave food on a plate.

According to the British Heart Foundation's Portion Distortion Report between 1993 and 2013, Shepherd's pie ready meals almost doubled in size and an individual chicken pie is now 40% bigger. A family pack of crisps has grown 50% from 100g-150g on average.

The team called on the government to introduce measures to force smaller packs to offer better value for money and upper limits on the size of energy-dense foods.
